- n/a, not applicable; SHBG, sex hormone-binding globulin; DHEAs, dehydroepiandrosterone sulfate.
- Data are arithmetic means (standard deviation) for continuous variables and percentages for categorical variables. Age-adjusted geometric means (95% confidence in intervals) are presented for hormone concentrations which did not follow a normal distribution.
